I have been working on a robot for a water chemistry project and have run into an issue. I was giving a Venterior Portable Fish Finder (Model VT-FF001) and was told to have it run via an Arduino Uno board. I have a large amount of supplies (tools, wires, breadboards, etc.) but I can not figure out how to finish this sensor. I would like the transducer to read the depths and report it back and I know how to do it with a typical Arduino Ultrasonic Sensor or with a Piezo Electric Transducer, but sadly those are not options. any ideas on the topic are greatly appreciated! I am brand new to Arduino and would really appreciate some pointers.
Thank you in advance,
